Exothermic reactions create bonds
Did you know?
WebIn some reactions the energy required to break bonds is larger than the energy evolved on making new bonds, and the net result is the absorption of energy. Such a reaction is said to be endothermic if the energy is in … WebApr 23, 2024 · Anytime a bond is formed energy is released ($\Delta H\lt0$), so forming bonds is exothermic. Try not to get the above $\Delta H$ 's mixed up with any $\Delta H_\mathrm r$. The above is relevant to breaking/creating single bonds; reactions are dynamic processes that are much more complicated that formulas make them appear to be.
